The Apostle Paul warned the Church--both ancient and modern--to recognize and defend against certain enemies: those who come against her from the outside and those who attack from within. Today, that warning still holds true but the greatest danger by far is not the Atheists, the Agnostics or even the anti-Christian mainstream media--the greatest danger is the corrupt and apostate shepherds who infest our seminaries and colleges and who stand in the way of anyone fighting to preach the Gospel.
"For the time will come when men will not endure sound doctrine but according to their own desires, because they have itching ears, they will heap up for themselves teachers; and they will turn their ears away from the truth, and be turned aside to fables." 2 Timothy 4:3-4
